Extreme Events

Within the context of global warming, remarkable climatic events act as a catalyst for concern whether the climate is changing. Indeed, remarkable climatic events regularly throw the media spotlight on the issue of global warming and its effects on their increase in frequency and intensity. To what extent such climatic events are really extraordinary and if their frequencies and intensities are increasing is a question still widely debated. The extreme data cover only the last decades and these rare events still largely fall within the domain of uncertainty. This is why we need to explore the past geological records to open wider the window of observation. By this mean, we might be able to provide significant and meaningful observations and data allowing analyzing the characteristics of extreme event occurrences. In addition, our working group believes that such extreme events also strongly dominate the source to sink transfer and therefore impact the tectonic processes of mountain building at different spatial and time scales. Within this research axis, we will consider as “Extreme Event” any catastrophic event that suddenly disrupts the environment. There will be three sub-axis allowing dealing with:

(1) Coastal dynamics, impact of typhoons and (paleo-) tsunamis;

(2) (Paleo-) earthquakes and (paleo-) landslides;

(3) Extreme weather events.
